Birkenhead Operations is a cement & lime facility operated by ADBRI LIMITED in SA. Like all covered facilities, cement production releases CO₂ from limestone calcination as well as fuel combustion. Under Australia's Safeguard Mechanism, Birkenhead Operations must keep its annual emissions below a stepping-down baseline — or purchase carbon credits to cover any overage.
In 2023–24, Birkenhead Operations came in under its baseline — reporting emissions of 809 kt against an obligation of 877 kt, a surplus of 29 kt. Facilities that come in under baseline can generate Safeguard Mechanism Credits (SMCs), which can be sold to facilities that need to cover an overage. Birkenhead Operations generated 29,000 SMCs in 2023–24.
